Which version of Event Gallery do you use?

1. Which Paypal method do you use? The basic one is very simple and should work out of the box. The Adaptive Payment plugin is way more complicated to manage since you need to create an Paypal Application and retrieve API access credentials for your account. Is the redirect to PayPal working? If so you configured the payment method in the right way. There is an paypal error log in Joomlas /log folder. I would like to have a look at it.
2. Just the disclaimer is German. You can change it in the components options and add your ownn. Don't get confused by the empty disclaimer field. If it's empty the copy comes from the language files.

This editor field is not a WYSIWYG editor. You need to add some HTML-Tags to split this text up.

<br> for line breaks.
<p></p> for paragraphs.

This will help to avoid this large text block. It's not that convenient, I know. Maybe I'll revisit this in later versions.

Regarding your PayPal integration: please check the error log I mentioned? It'll help you finding the issue. The redirect will fail if you entered the wrong credentials. There are several pit falls:

Did you get the PayPal API key by mail?
Did you get the API Access credentials by mail?
Do you use the sandbox mode? Does the sandbox mode work at all?

For most of the users the PayPal Basic method is easier to use.

Please send me the paypal error log by mail if you still need help with this. Keep in mind this is a public ticket.
